Denver’s airport among the top two worst for delays in all of the U.S.

It may feel like flights out of Denver International Airport (DIA) are delayed more than most airports, but that could just be because it’s our home airport and we don’t fly out of others as often… Or is DIA just really that prone to delays?

It seems as though the latter is likely the case. According to a recent report from AirHelp, an air passenger rights and flight tracking company, DIA is the second worst airport in the U.S. for delays.

According to the report, Chicago O’Hare International Airport (ORD) experienced the most delays of any U.S. airport in 2025 with 28 percent of all flights delayed. Here are the airports that experienced the most delays in 2025 and the percentage of flights departing from those airports that saw delays:

1. Chicago O’Hare International Airport (ORD): 28 percent
2. Denver International Airport (DEN): 27 percent
3. Miami International Airport (MIA): 26 percent
4. New Jersey’s Newark Liberty International Airport (EWR): 26 percent
5. New York’s LaGuardia Airport (LGA): 26 percent
6. Philadelphia International Airport (PHL): 26 percent
7. Ronald Regan Washington National Airport (DCA): 26 percent
8. New York’s John F. Kennedy Airport (JFK): 25 percent
9. Orlando International Airport (MCO): 25 percent
10. Washington Dulles Airport (IAD): 25 percent
